Just thinking about Sherlock Holmes and James Moriarty, the archrivals from the original story, both faking their deaths today was almost enough to make Iver lose his composure.
However, Iver keenly caught a blind spot in his perspective.
The reason Lawyer York could directly confirm that Sherlock was dead was simple—he was the one who had personally done it. He had drugged Sherlock with sleeping pills, then detonated the sufficient quantity of explosives he had prepared at the time the drugs took effect. He had also received news of Sherlock's death at a reasonable time.
From this perspective, the fundamental reason he could confirm Sherlock's death... was actually because Lawyer York sincerely hoped it was true.
Although Consultant York appeared to hold a relatively high position within Lloyd's, his current situation was actually quite difficult. He absolutely could not expose himself in this case, yet he had to personally kill Sherlock.
As long as the explosion failed to kill Sherlock, whether he went back to finish the job or not, he would risk exposing himself. Therefore, he did not want to hear news that Sherlock had survived—so he would subconsciously use the intelligence he had gathered to confirm the conclusion he had already reached. This was also preparation he had made in advance to convince the other high-ranking members.
From this perspective, if Lloyd's could confirm that Professor Moriarty was dead... did that mean they had also participated in the matter?
After all, divination could be disrupted and was not necessarily completely accurate. Furthermore, those at too low a level could not accurately divine the fate of those at a higher level. Since Lloyd's could invite a prophet to divine for them, they surely knew about these limitations.
If they could confirm the death without verifying the corpse... then they
